General Description

The LTC®2142-12/LTC2141-12/LTC2140-12 are 2-channel simultaneous sampling 12-bit A/D converters designed for digitizing high frequency, wide dynamic range signals.

They are perfect for demanding communications applications with AC performance that includes 70.8dB SNR and 89dB spurious free dynamic range (SFDR).

Ultralow jitter of 0.08psRMS allows undersampling of IF frequencies with excellent noise performance.
